AN OVERVIEW OF THE MT-800
The MT-800 (Figure 1-1) is an eight port transceiver designed to link
up to eight network or host devices together. The MT-800 allows these
devices to communicate with a network or just between themselves.
The MT-800 is compatible with specifications for a 10 Mb/s Medium
Access Unit under Ethernet Versions 1.0 and 2.0, and IEEE 802.3
standards.
The MT-800 works in two modes - Local or Network. In the Local mode,
the MT-800 only receives and transmits traffic from the devices
attached to it. This mode is enabled by the Loopback (LBK) switch on
the front of the MT-800.
The MT-800 can also be configured with another transceiver to allow
the devices attached to it to communicate with a larger network. The
other transceiver could be attached to a thick or thin coax cable, a fiber
optic link or a twisted pair segment.
The MT-800 contains nine AUI ports. Ports 1-8 connect the MT-800 to
network devices or host units. These eight ports act as transceivers.
The ninth port allows the MT-800 to be connected to an external
transceiver, giving the other devices access to the network.
The MT-800 can also be configured in a cascaded method with a second
layer of MT-800s. Up to eight additional MT-800s could be connected
through one MT-800, allowing up to 64 users.
